# ExplosionMotor vs RunPee

The clearest difference is price: RunPee at Free against ExplosionMotor's $0.99. RunPee also leads on rating (4.8 vs 4.0) and update cadence (every 3 months vs every 39 months). ExplosionMotor's advantage is in-app purchases (none vs 10) and review sentiment (100% vs 83%). On ads, device support and iOS requirement there is nothing between them.

RunPee is free to download; ExplosionMotor costs $0.99 up front. RunPee sells 10 in-app purchases, starting at $0.99 per month. ExplosionMotor asks for nothing beyond the download.

RunPee holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: RunPee has 545 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of ExplosionMotor's written reviews are positive against 83% of RunPee's, so the app with the better star average is not the one people write more warmly about.

ExplosionMotor ships an update every 39 months, RunPee every 3 months. The most recent releases landed on November 1, 2026 and November 6, 2026 respectively.
